IMPROVEMENT lN .CHURNS.

Specication forming part of Letters Patent No. 58,228, dated September25, 1866.

To all whom it may concern:

Be it known that I, FRANoIs DANZENBAKER, of Bridgeton, in the county ofCumberland and State of New Jersey, have invented a new and usefulImprovement in Ghurns 5 and I do hereby declare that the following is afull, clear, and exact description of the sa1ne,.refer ence being had tothe annexed drawings, making'part of this specification, in which-Figure l is partly in perspective and partly a vertical section, andFig. 2 is a vert-icalseotion.

The same letters are employed in referring to identical parts.

The dasher of the churn is applicable to the common churn. A is thehandle, which is hollow, being made of a metallic or other tube, openthrough its entire length. The upper end of this tube is closed byV astopper, B, f1tting the same. This stopper is cut away on one side atits lower end, as shown at C, the lower part of the face being vertical,or nearly so. An opening, E, passes through the stopper from the Eatportion 0,011 which is attached the flap-valve D, of india-rubber orother suitable material. There is a hole, .corresponding to this openingE, through the case of the tubular dasher A. When these openings are inconjunction the air can. pass from the outside through the valve D intothe hollow portion of the tube, and thence downward into the cream belowthe. dasher. This will occur whenever the dasher is raised, as a partialvacuum would then be created below the center of the dasher, causing theair to iiow the case of the tube A, when the air is completely excludedbythe stopper B, which ts closely to the inside of the tube to a pointbelow the opening. The work is then completed as in the ordinary churn.The same effect may be produced by using a perforated cap over the tubeinstead ot' a stopper within it.

I do not claim -the use of airintroduced through the dasher andregulated by a valve, for that I know has been done by others; but

What I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the tubular'handle A, adjustable stopper B,or itsequivalent, and valve D, when constructed and arranged to loperatesubstantially as set forth.

In testimony whereof' I have 4signed my name to this specification inthe presence of two subscribing witnesses.`
